Trend drawings - Averaging

Hi to everyone,
I’ve got a problem on my plant, so I’m tracing a lot of pens to take care of it.
I have to control if the routine I’ve written is doing well in calculate weight on a multi-level tank (the tank has separators inside) with only one weight transimtter: I activate the campute only when dedicated valve opened.
Timing is important and value too, but in trend I cannot achive that!

If you look at the query browser you see that there’s no point between 2018-09-14 17:08:43 and 2018-09-15 04:14:43 but the graph indicate a slow ramp!
At first look seems my routine wash wrong, but was not: this data has been “invented” by the averaging function! :frowning: :frowning:

I can not afford it
How I can disable it?
